First Ray

The authors present a quantitative analysis of the effect that first ray position has on motion of the first metatarsophalangeal joint. A goniometer was constructed to measure the degrees of first metatarsophalangeal joint dorsiflexion with the first ray in three positions: weightbearing resting position, dorsiflexed 4 mm from the weightbearing resting position, and dorsiflexed 8 mm from the weightbearing resting position. First metatarsophalangeal joint dorsiflexion decreased 19% as the first ray was moved from the weightbearing resting position to 4 mm dorsiflexed, 19.3% as the first ray was moved from 4 mm dorsiflexed to 8 mm dorsiflexed, and 34.7% as the first ray was moved from the weightbearing resting position to 8 mm dorsiflexed. The biomechanical significance of decreased first metatarsophalangeal joint dorsiflexion that results from first ray dorsiflexion is discussed, and proposed bases for the pathomechanics of hallux abducto valgus and hallux rigidus deformities are presented.

First Ray

The first metatarsophalangeal (MTP1) joint fusion is a very useful procedure in forefoot surgery and is still the gold standard for the treatment of severe and painful hallux rigidus. Normal walking and running are possible after MTP1 fusion, the first ray mobility being essentially in the interphalangeal (IP) joint with a compensatory hypermobility in dorsal flexion. Percutaneous MTP1 fusion is a simple procedure providing comparable results to fusions performed with open techniques. Postoperative cares are simplified with an immediate full weight bearing on rigid flat shoes and quick return to normal walking. Bone preparation is an important step and requires an experience in percutaneous forefoot surgery. Arthrodesis positioning and fixation with this percutaneous procedure are simple with possibility of clinical and radiological control. The indications for percutaneous MTP1 fusion are very large and only severe bone loss or osteoporosis represent the limits for this technique.

The Relationship

Reduction in first metatarsophalangeal joint maximum degree of dorsiflexion with dorsiflexion of the first ray has been proposed to be the predominant cause of hallux abducto valgus and hallux rigidus. We sought to determine whether orthoses made from a cast with the first ray plantarflexed and a 4-mm medial skive could increase the maximum degree of dorsiflexion in patients with functional hallux limitus in stance and gait. Forty-eight feet of 27 subjects were casted for orthoses with the first ray plantarflexed and in the customary neutral rearfoot position with locked midtarsal joint. First metatarsophalangeal joint maximum dorsiflexion was measured with and without orthoses in stance, and subhallux pressure was measured with and without orthoses at heel-off. Changes in mean maximum dorsiflexion in stance and in mean maximum subhallux pressure in gait with orthoses were significant. We investigated the relationship between this increase in dorsiflexion and gender, shoe size, resting calcaneal stance position, and change in resting calcaneal stance position with the use of orthoses. These correlations were not statistically significant. The biomechanical implication of increasing limited first metatarsophalangeal joint dorsiflexion with orthoses is discussed and related to the clinical treatment of deformities, including hallux valgus and hallux rigidus. The use of orthoses to decrease subhallux pressure is also discussed. (J Am Podiatr Med Assoc 96(6): 474–481, 2006)

Biomechanical Evaluation

Hallux rigidus produces a decrease in the dorsiflexion of the first metatarsophalangeal joint and is usually associated with the appearance of osteophytes. Hemiarthroplasty in the first proximal phalanx is a recommended surgical procedure in patients with advanced grade of hallux rigidus. Finite element analysis allows us to understand the biomechanical behavior of the foot. The objective of this work is to evaluate the biomechanical effects of an hemi implant placed in first proximal phalanx. Two models of finite elements are going to be compared, one free of pathologies and the other with a hemiarthroplasty in the first ray of the foot. We detected after inserting the prosthesis in the model that passive windlass mechanism is lost, and the lesser toes become overloaded, which leads to a loss of efficiency in gait as well as being able to cause postsurgical medical complications.

Category: Bunion, Midfoot/Forefoot Introduction/Purpose: Hallux rigidus is a degenerative disease of the first metatarsophalangeal joint. Severe, end-stage hallux rigidus can become debilitating with surgical intervention becoming necessary once conservative measures and shoe modifications have failed. Joint salvage procedures include metatarsal phalangeal (MTP) arthrodesis and MTP arthroplasty. The purpose of this study was to assess for differences in patient reported outcomes in two cohorts who underwent fusion or joint reconstruction. Methods: This study was a retrospective review of prospectively collected data of 385 patients from an academic medical institution. Patients who underwent surgical intervention from July 2015 to November 2016 were identified based on CPT codes for MTP arthrodesis (28750) and arthroplasty (28293). We extracted outcome scores including SF12-M, SF12-P, FAAM, and VAS scores. Exclusion criteria included poly-trauma, revision procedures, and lack of pre and post-operative outcome scores. Mann- Whitney t-test was performed using GraphPad Prism version 7.0b for Mac to compare procedure groups, with significance define by a p-value of 0.05. Results: A total of eighteen patients met the inclusion criteria, with 6 who underwent arthroplasty and 12 arthrodesis. The average age was 63.7 amongst the cohort, with a total of 16 female and 2 males. Patients who underwent arthrodesis had better outcomes across all parameters. When comparing preoperative and postoperative scores, arthrodesis patients showed greater improvement of SF12-M (arthrodesis 9 vs arthroplasty -2, p=0.05), and SF12-P (9 vs -16, respectively p=0.05) scores. Arthroplasty patients were more likely to have a decrease in their SF-12 scores. VAS scores and FAAM scores showed no statistical difference between the two cohorts. Postoperative VAS scores were worse in 33% of arthroplasty patients despite surgical intervention, compared to 10% of arthrodesis patients. Conclusion: Our results suggests that both procedures provide a statistically significant difference in pain with several patients having a Global Rate of Change that is “very much better”. However, fusion of the metatarsophalangeal joint results in improved pain and functional outcomes for patients with severe hallux rigidus. These findings are consistent with current reports in the literature, which are mostly case series reports. Larger studies are needed to provide appropriate power and better support the findings of this study.

A retrospective radiographic review was performed of 29 patients (37 feet) who underwent an isolated medial approach for correction of hallux abducto valgus deformity from March 1993 to November 1998. Only those patients who had a traditional Austin-type osteotomy with a reducible first metatarsophalangeal joint and flexible first ray were included in the study. The average follow-up period for the entire study group was 18.4 months, with 13 patients (44.83%; 17 feet) having a follow-up period of longer than 2 years. The average decrease in the intermetatarsal angle was 9.89°, and the average decrease in the hallux abductus angle was 14.0°, results that correlated well with those of other studies on correction of hallux abducto valgus. No clinical or radiographic recurrence of hallux abducto valgus was noted throughout the follow-up period. The authors believe that an isolated medial approach to hallux abducto valgus correction without a lateral interspace release yields predictable results when performed in appropriately selected patients.

Meta Analyses

Abstract Background With continued loss of dorsiflexion of the 1st MTP, degenerative changes occur within the joint with severe restriction of movement and increase in pain, which leads to the condition known as hallux rigidus. The amount of dorsiflexion may be reduced to 0-10 degrees with pain on both active and passive motion. Objectives Systematically reviewing available evidence from published articles to assess the effectiveness of arthrodesis of first metatarsophalangeal joint by plate and screws in hallux rigidus. The assessment also would encompass safety, side effects, and complications of this mode of treatment. Materials and Methods We performed this systematic review and meta-analysis in accordance to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and Meta-analysis Of Observational Studies in Epidemiology (MOOSE) statement. PRISMA and MOOSE are reporting checklists for Authors, Editors, and Reviewers of Meta-analyses of interventional and observational studies. According to International committee of medical journal association (ICJME), reviewers must report their findings according to each of the items listed in those checklists. Results Previous results for arthrodesis have been favourable with a union rate of almost 96%. In the present systematic review and meta-analysis, the overall effect estimates showed that the union rates after plate and screw arthrodesis for 1st MTPJ was 96.2% (95% CI 94 – 98.4%). In addition, the overall effect estimates showed that the non-union rates after plate and screw arthrodesis for 1st MTPJ was 4.2% (95% CI 2.4 – 6.1%). Moreover, the overall effect estimates showed that the satisfaction rates after plate and screw arthrodesis for 1st MTPJ was 94.5% (95% CI 90 – 99%). In the present study, the overall effect estimates showed that the overall complications rate after plate and screw arthrodesis for 1st MTPJ was 7.2% (95% CI 2.5 – 12%). The overall effect estimates showed that the malunion rates after plate and screw arthrodesis for 1st MTPJ was 2.7% (95% CI 0 – 6.4%). Additionally, the overall effect estimates showed that the hardware removal and superficial infection rates after plate and screw arthrodesis for 1st MTPJ were 2% and 2.9%, respectively. Conclusion Our analysis showed that plate and screws fixation is effective techniques that can be used for first MTPJ arthrodesis in patients with hallux rigidus. We found that the screw and plate fixation has a significantly lower rate of nonunion compared with the screw alone, as reported by the literature. However, owing to the small group sizes and methodologic shortcomings, we were unable to identify the clinically superior fixation technique for first MTPJ arthrodesis arthrodesis.

Objective: The objective of this study was to describe the percutaneous arthrodesis technique with single medial portal of the first metatarsophalangeal joint and to evaluate the results of a series of nine cases (10 feet) with a diagnosis of hallux rigidus subjected to this technique, comparing the results with literature data regarding the conventional technique. Methods: This was a retrospective, observational study performed by analysis of medical records and radiographs of nine patients undergoing percutaneous arthrodesis of the hallux metatarsophalangeal joint. Gender, age, consolidation time, level of postoperative pain and degree of patient satisfaction were evaluated. Results: Eight patients were female, and one patient was male. The mean age was 68.7 years, the mean consolidation time was 8 weeks, the consolidation ratio was 70%, there was pain improvement in the postoperative period, and all patients considered themselves satisfied with the surgery. Conclusion: Percutaneous arthrodesis of the metatarsophalangeal hallux joint potentially yields results similar to those of the conventional method demonstrated in the literature but uses smaller incisions.Level of Evidence IV, Therapeutic Studies, Case Series.

Forefoot surgical outcomes were evaluated in 26 patients with rheumatoid arthritis. A total of 45 procedures were reviewed with emphasis on first ray intervention. Disease duration and aggressiveness of preceding medical therapy were combined to establish a disease severity index. Patients operated were predominantly in the midrange of disease severity. Subjective data on the relief of pain, callus, and deformity were favorable but this benefit was not long lasting inasmuch as patients were most satisfied in the period immediately following surgery and less so as time elapsed from intervention. Fusion of the first metatarsophalangeal joint seemed better than resection alone, indicating that stability should be the primary goal for surgical intervention of the rheumatoid forefoot.
